Lesson 047: Booleans, comparisons, and truthiness

Focus

Slow tempo wins; narrate checkpoints aloud: Basic drills Booleans, comparisons, and truthiness; spin token 394219 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 7 mixes Booleans, comparisons, and truthiness; spin 47990.
Ritual: Mirror the snippet with reversed iteration order verbally.
Guardrail: call out latent off-by-one before shipping analogues.

Example (`LESSON_UID = "basic-047"`)

# Basic drill L047 topic-4 micro-6 pattern-5
LESSON_UID = "basic-047"
spin_a, spin_b, spin_c = 791, 242, 86

hop = (spin_a % 13) + 6 + 4
total = (spin_b + 47 * spin_c) % 5003
while hop < (908 % 61) + 30:
    total += hop
    hop = hop * (614 % 5 + 1) % (spin_a % 127 + 6 + 17)
    if total % (spin_b % 17 + 6 + 11) == 0:
        break
print(total, hop)
